Floodplain Maps Update
The Federal Emergency Management Agency (FEMA) recently updated the old paper floodplain maps throughout Wyandotte County and Kansas City, Kansas to digital. The primary purpose of updated information is to establish Flood Insurance Rate Maps, which show only the floodplain of larger rivers and streams. Localized flooding, such as runoff from a neighbor's yard or backups from sewers, is not addressed with these maps. The Unified Government adopted the new floodplain maps by FEMA on September 2, 2011.
There have been a number of memorable flood events within Wyandotte County. The 1951 flood was the result of a deluge of epic proportions. It had been wet all spring and early summer in Kansas, and the rivers were running full. A series of monster storms, beginning July 9th and ending July 13th, left more than a foot of rainfall over much of eastern Kansas. The great flood of 1993 constituted the most costly and devastating flood to ravage the United States in modern history. Levees were broken, farmland, town, and transportation routes were destroyed, thousands of people were forced to abandon their homes, and 47 people died as a direct result of the flood. June 2011 flood had two levee breaches and impending interstate closings.

Development/Construction Within a 100 year Floodplain or Floodway Requires Review and a Permit
Residential or commercial construction (new, addition, or fill) within a 100 year floodplain or floodway requires review and permits from Urban Planning and Land Use, Building Inspections Department and/or the Development Review Committee (DRC). Development is defined as: any man-made change to improved or unimproved real estate, including but not limited to buildings or other structures, mining, dredging, filling, grading, paving, excavation or drilling operations or storage of equipment or materials located within the area of special flood hazard.
The following shall be required during the permit review and construction phases of the project:
Detailed plot plan/site plan designed by a Kansas licensed surveyor, architect, and/or engineer showing current and proposed site conditions, utility lines, utility easements, right-of way, grades and designated base flood elevation (2 foot intervals), finish floor elevation, FIRM map panel number and year, and any documentation of Federal Emergency Management Agency related documents required for the review of the project (supporting documents such as a Letter of Map Change (LOMC).
During construction a certificate of elevation shall be provided at the rough-in phase. No rough-in inspections will be allowed until the certificate of elevations is reviewed and approved by the Floodplain Administrator or his/her designate. If required, certification for flood proofing, wet flood proofing, and/or a no-rise certificate may be required.
At the time of a temporary (TCO) or final certificate of occupancy (CO) a final certificate of elevation shall be submitted for review and shall be approved by the Floodplain Administrator or his/her designate before a TCO or CO can be issued.
Any supportive documents for the project such as a LOMC shall be provided for review.
